| 在头文件 <string.h> 中定义
|
||
| char *strncpy( char *dest, const char *src, size_t count ); |
||
count字符的字节串的副本指出,src(包括终止空字符)的字符数组指出,dest. 原文:
Copies at most
count characters of the byte string pointed to by src (including the terminating null character) to character array pointed to by dest. count达到之前的整个字符串src被复制,产生的字符数组是不是空终止原文:
If
count is reached before the entire string src was copied, the resulting character array is not null-terminated.之后,如果从
src终止空字符复制,count没有达到,额外的空字符,直到总的dest字符写入count已经写.原文:
If, after copying the terminating null character from
src, count is not reached, additional null characters are written to dest until the total of count characters have been written.如果字符串重叠,该行为是未定义.
原文:
If the strings overlap, the behavior is undefined.
